Abstract
The utility model discloses a kind of involute spline eccentric shaft processing unit (plant), it comprises knife rest; Knife rest is connected with fixed head by back-moving spring; Fixed head is provided with small tool handwheel; Pattern arm is had to be fixed on knife rest by clamp nut; Pattern arm is provided with synchronous pattern wheel; Knife rest is provided with lathe tool.Lathe spindle right-hand member is had to be connected with two eccentric master plate; Two eccentric master plate right-hand member is connected with pusher dog, front thimble; Pusher dog end is provided with spline heart and accompanies double-eccentric shaft and locate fixing by pusher dog, front thimble; Fixed by tailstock center on the right side of double-eccentric shaft.Because the fit tolerance of involute spline heart carrier for bolt and involute splined shaft is 5H/5h, the height point on a tooth of the involute spline processed and involute spline eccentric shaft is consistent.Solve the height point orientation problem on spline tooth and spline eccentric shaft.Because the eccentric precision of workpiece depends on the eccentric precision of master plate, do not affect making precision by human factor, therefore reliable and stable.
Description
Technical field
The utility model relates to machinery processing apparatus, refers to a kind of involute spline eccentric shaft processing unit (plant) particularly.
Background technology
The precision of current eccentric shaft processing technology eccentric shaft processing, the problem such as directed in eccentric throw, high point affects comparatively large by the human factor of operating personnel, and the precision of same lots processed part is difficult to guarantee, and production efficiency is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of involute spline eccentric shaft processing unit (plant) not being affected by human factors precision.Involute spline eccentric shaft and double-eccentric shaft, have phase difference to be the double-eccentric shaft eccentric part of 180 degree; Double-eccentric shaft left end is provided with double-eccentric shaft spline.
The utility model clicks technical scheme and realizes:
A kind of involute spline eccentric shaft processing unit (plant), it comprises knife rest; Described knife rest is connected with fixed head by back-moving spring; Described fixed head is provided with small tool handwheel; Pattern arm is had to be fixed on described knife rest by clamp nut; Described pattern arm is provided with synchronous pattern wheel; Described knife rest is provided with lathe tool.
Lathe spindle right-hand member is had to be connected with two eccentric master plate; Described two eccentric master plate right-hand member is connected with pusher dog, front thimble; Described pusher dog end is provided with spline heart and accompanies double-eccentric shaft and locate fixing by described pusher dog, described front thimble; Fixed by tailstock center on the right side of described double-eccentric shaft.
Usefulness of the present utility model is, because the fit tolerance of involute spline heart carrier for bolt and involute splined shaft is 5H/5h, the height point on a tooth of the involute spline processed and involute spline eccentric shaft is consistent.Therefore, the height point orientation problem on spline tooth and spline eccentric shaft is solved.With pattern processing involute spline eccentric shaft, because the eccentric precision of workpiece depends on the eccentric precision of master plate, do not affect making precision by human factor, therefore reliable and stable.
